MAGNETIC SENSITIVITY TRANSFER CURVE
2
The magnetic sensitivity transfer curve illustrates the characteristic behavior of an analog TMR sensor’s resistance change as the strength of an applied magnetic field changes. The magnet approach curve (blue line) shows the change in resistance as the strength of an applied magnetic field increases. The magnet recede curve (red line) shows the change in resistance as the strength of an applied magnetic field decreases. Alternatively, you can think of the resistance going down the blue slope as a magnet approaches the sensor, and going up the red slope as the magnet moves further away from the sensor. 65

TMR TECHNICAL & APPLICATIONS INFORMATION GLOSSARY OF TERMS Hysteresis: Hysteresis refers to the difference between two points of interest for a particular device. For digital sensors and switches, it represents the difference between the operate sensitivity and the release sensitivity, expressed either as an absolute value (Bop – Brp) or the % difference (Bop – Brp)/Bop. For an analog sensor, the hysteresis is the difference between the “magnet approach curve” and the “magnet recede curve.” Magnet Approach Curve: The magnet approach curve is the characteristic change in resistance of an analog TMR sensor as an applied magnetic field approaches the sensor, typically plotted as a function of the magnetic field strength.
Operate Sensitivity: The operate sensitivity defines the upper limit of the strength of an applied magnetic field that a digital TMR sensor or switch must operate. Operate Time: The operate time is the difference, in time, between the application of a magnetic field and the output response of the device. In an analog sensor, the response is a change in output resistance. In a digital sensor, the response is a change in state of the electrical output. Release Sensitivity: The release sensitivity defines the lower limit of the strength of an applied magnetic field that a digital TMR sensor or switch must release.
Magnet Recede Curve: The magnet recede curve is the characteristic change in resistance of an analog TMR sensor as an applied Release Time: The release time is the difference, in time, between magnetic field recedes from the sensor, typically plotted as a function the removal of an applied magnetic field and the output response of of the magnetic field strength. the device. In an analog sensor, the response is a change in output resistance. In a digital sensor, the response is a change in state of the Magnetoresistance: Magnetoresistance is a phenomenon electrical output. wherein the electrical resistance of certain materials changes when exposed to an externally-applied magnetic field. Tunnel Magnetoresistance (TMR): Tunnel Magnetoresistance is the magnetoresistive effect that occurs in a magnetic tunnel Magnetic Transfer Curve: The magnetic transfer curve defines junction. the characteristic behavior of an analog TMR sensor by combining both the magnet approach curve and the magnet receive curve together. Magnetic Tunnel Junction: A magnetic tunnel junction is a thin film structure consisting of two magnetic layers separated by a thin insulator. Because the insulating layer is thin enough (typically a few nanometers), electrons can tunnel from one magnetic layer into the other.

MAGNETIC SENSITIVITY MAPS Magnetic sensitivity maps show the operate and release loci in threedimensional space when a magnet is presented to a magnetically operated switch or sensor. The absolute operate and release distances between the magnet and the sensor will vary depending on the sensitivity of the switch and the strength of the magnet. However, the shape and direction of the operate loci stay relatively constant except
for cases where the magnet is physically much larger than the sensor. These plots were generated using a 2mm^3 cubic shaped NdFeB N52 magnet with its North pole presented to the ground pin and a South pole presented to the opposite side. The X, Y, and Z axes have their origin (0,0,0) at the geometric center of the TMR device.
